The arterial end of the Oxygen is diffusing into the Oxygen diffuses into the capillary has oxygenated The Pco2 in the arterial end of the capillary is 46 mmHg blood Carbonic anhydrase is carbonic acid plasma The arterial end of th blood blood amount of capilary has deoxygenatedyen dissociates from the oxyhemoglobin molecule Oxygen dissociates from the Carbon dioxide is diffusing into the blood Alveolar Capillaries Systemic Capillaries

Explanation / Answer

1.There are two types of respiration are there. They are internal respiration and external respiration.

2. The internal respiration is exchange of gases between blood and tissue (systemic capillary), where as external respiration is exchange of gases between pulmonary capillary to alveoli (Alveolar capillary)

3. In internal respiration exchange between blood and tissue cells oxygen is unloaded and carbon dioxide loaded into blood as carbonic acid.

4. Carbonic anhydrase is the enzyme which converts CO2 to HCO3. This bicarbonate diffuses out into plasma and oxygen released from Hb and diffused from blood.

5. System capillaries are poor in oxygen and rich in CO2 , so this CO2 is diffusing into the blood..

6. Alveolar capillaries: 1. Oxygen is diffusing into the blood 2. Oxygen diffuses into the plasma.

3. Carbonic anhydrase is increasing the amount of carbonic acid.

4. The PCO2 in the arterial end of capillaries is 46 mmHg

7. System capillaries: 1. The arterial end of the capillary has oxygenated blood. 2. Oxygen dissociates from the oxyhemoglobin molecule

3. The arterial end of the capillary has deoxygenated blood

4. Carbon dioxide is diffusing into the blood.

8. the above are the conditions pertaining in alveolar capillaries and systemic capillaries.
